From the artist:

Well just like that I’ve trapped myself into another series of stressful evenings… Ah hell Christmas is always Stressful. I’ll be winging it again this year, I wanted to get back into pointy ponies this year, maybe try and do some stuff with the new horses but I ran out of time so maybe next year. Anyway on with the more normal advent calendar I promised.
